Customise, localise and extend an HTML5 game
Plan artwork changes, language support and new levels using editable source and the tools included with a game.
Start from a working build and change one part at a time. A small, verified change is easier to diagnose than replacing artwork, rules and translations together.
Artwork and branding
Check asset dimensions, transparent edges, sprite sheets and loading manifests before replacing files. Match file names and formats or update their references. Test the smallest supported screen, and keep required third-party notices. Review asset rights and any AI asset disclosures for the version you purchased.
Languages
Game localisation and website translation are separate. Use the game’s locale files or editor, then test long labels, line wrapping, fonts and numbers in every supported layout. Adding a translation file does not prove right-to-left layout or full script coverage. Ask a fluent reviewer to check the result.
Levels
A built-in level editor can make puzzle changes easier. Where included, create a draft, run validation and solution checks, playtest it and export the supported format. Local in-game admin tools normally affect that browser’s data; they are not a hosted service for managing players.
Build and verify
Rebuild using the supplied instructions, then test a new session and an existing save. Confirm that customised assets, translations and levels are included in the final export. Keep the original project and licence alongside your changes.
